`This invention relates, generally, to improvements 1n-mus`ic-stands; and, the' present invention has reference, more'particularly, f to a novel andl simply constructed musicstand,the various members of which arereadilyycollapsible orfoldable, so asfto provide a -1nusic-'stand, `the parts of which, when the 'stand lis not in use, can be disposed so as to occupy a minimum space, and to provide a small package which* can be carried about without inconvenience to the musician;

"The ypresentA invention, therefore, yhas for 'itsprincipa'l objectl 'toprovide a music-stand, the V-varousparts of which arereadilyy separable and collapsible, for arrangement of the parts in a small' package, when thefstand isV not in use, but .the parts of which can be easily and quickly-"brought into :their ad-v v.will be clearly .understood from the following detailed description ofthe said invention.

Vith thevarious objects'ofthe present inv vention in view, the said invention consists, primarily, in thenovell collapsible musicn ao standv hereinafter set forth', and, the said invention consists, furthermore. in the novel arrangements and combinations ofthe sevf eral` vdevices and parts, as iwelll as inthe details fof' the construction Vof the said parts,

j v fall ofwhich will' be more fully'described in thej'fol'lowing specification, and then vfinally g embodied in the clauses of the claims, which are appended to and which form .an essential part of the said specification.

'Ih'e'invention is illustrated in the accom-4 panyingdrawings, 1n wh1ch':-

Figure 15 isa detail view, partly in elevation and partly in vertical section of the lower` tubular member of the standard, and

a connector-slide thereon, illustrating another modified means forsecuring said slide in a fiXedfp'ositi-on upon said tubular member.

Similar characters of reference areemployed in all of the said above ydescribed views, to indicate corresponding parts.

Referring now to the said gures of the suitable lengths and any desired cross-sec,-V

tion. It will be understood, however, Vthat this number of members 'or extensionsmay be increased, if desired.

Atits lower extremity, the saidv tubulary gularly and rigidly securing the said musicmember or extension 2 is provided withl a bead, Vas 4, or other suitable stop, upon which rests the lower end-portion or" a coiled spring 5, the said spring loosely encircling thelower Y portion of the said member or extension 2, and being disposed between the said stop 4 f and a pin 6, or the like, extending laterally across the said member or vextension 2, sub-V stantially as shown in Figures l, 7.and 9 ot the drawings. At itsfupper end-portion, the member or extension 2 is provided in its opposite sides with longitudinally extending slots 7, and in its lower end-portion, the member or extension 3 is also providedin its opposite sides with longitudinally extending slots 8, in registration with the said slots 7.

i Spring-members, as 9, are secured bymeans of pins 10, or otherwise, within the tubular end-portion of' said 'member or extension3,

each spring-member9 being provided withy an outwardly extending and suitably shaped retainingy member, or bowed portion 11, adapted, when the members or extensions 2 and 3 have been brought into their extended relation, to project into the registering slots Sand 7 and thereby rigidly maintaining the telescopically arranged members or' extensions 2 and 3 in their extended relation shown in said vFigure 1 of the drawings, andias will be clearly understood,fromk an inspection orp Figure 6. kTo slide the said member or extension 3 into its collapsed relation with the member or extension'2, pressure is applied by the operator upon the oppositiely bowed'portions 11 of the said spring-members 9, so as to torce said bowed portions 11 out ot vtheir holding or retaining engagement from the portions bounding the 'slots 7 ot the tubular member or extension 2, which permits the said member or extension 3 to be slipped down into the said member or extension 2, into a collapsed or nested relation therewith, as will be clearly understood. I am aware, of course, that in lieu ot this forni of retaining means,

other suitable construction of retaining means may be employed for securing kthe several Vtelescopically arranged tubular members or extensions in their extended relations, and tor permittingy theY same to be brought into aj closed or collapsed relation. At its -upper exf erence-character 13, and the same comprisesy a centrally disposed plate or bar 14, formed f i at a suitable point with a rearwardly extending strap, as 15, preferably pressed out of the said plate or bar 14, which provides a receiving socket` for the reception of the said'bent end 12 of the member -or extensionV 3, for anholder or rack in its detachable or separable relation toV the extended members of the standard of' the music-stand, as will be clearly evident. Pivotally mounted upon suitable pins or rivets 16 at the upper end-portion of,

toV

the said plateor bar 14 is a pair of oppositely extending arms 17and similarlyrmounted upon suitable pins or rivets 18Y at the lower end-portion of said plate or bar 14 isa pair y `of oppositely extending arms19, s aidarms being formed along their lower marginal edges with right-angled klianges 20, whereby suitable supports are provided for the placing et sheets or books of music thereon, vas will be evident.

are provided with pivot-pins or rivets 21, and i the said flanged supporting arms 19 are sim'- yilarly provided at their outer ends with pivot# pins or rivets 22; lPivotally mounted upon the vpivot-pins 21 Yofthe respective, arms 17 are links 23, and pivotally mounted upon the ypivot-pins 22 of the respective supporting arms19 are other links 24, each pair of links 23 and 24 being also respectivelypivotally connected by means of pivot-pins kor rivets, as 25. rIhis arrangement of the variousmembers permits the music-holder or rack tovbe brought into its opened-out position indicated in Figure 1 of the drawings; kor,-when the members are moved inwardly toward the plate or bar 14,'as indicated in the dotted outline in said Figure 1, then `the said 'membersY of the music-holderor rack mayv be brought into their foldedor closed relation, V.as indi-v Y catedin Figure 3 of the drawings..v

Slidably mounted upon they tubular extension 2 is a sleeve 26, which is transverselyslotted, as at'27,and as indicated in Figures 10' andA 11 of thedrawingsfthe 'said sleeve '4 being also rotatably mounted uponl said exT Y Ving into and through theslots'or grooves 27 of said sleeve 26inithe manner and-'for the purposes hereinafterV more fully specified', As shown, the said sleeve 26, is also provided:

with suitably spaced and radially projecting i313 i Y Y k 'At their outer end-portions, the arms 17 Y "l-arly kcut away at their upper extremities, as

`ears ori lugs 28 with which arepivotally'co'n- Y nected,by means ofipivot-pins 29, or in any other suitable manner, substantiallyas il- Alu'strated inFigures 1, 7,' 9 and 11, the upper end-portions ork extremities. of suitable sup por-,ts orlegs 30.'V The said supports orlegs, which are preferably made of a light material, fas aluminum, are usually made in the :form of aiigle-iron, the iianged members 31 of the said ysupports or legs 30 being anguat32, to provide suitable retaining or lock- 'fi p ends, adapted to be made to enter and engage the inner cone-shaped bore-portions `34; of'another anda locking sleeve, as 33, as

shown ,in said Figure; 9, and for the pur poses'hereinafter more fully described. This .last-mentioned sleeve 33 isk also slidably Yup the Kstand forv use by the musician, and ywhen not in use bringing the several mem- ,bei's of the stand into their folded and collapsed relation, forbringing the device into a Vsmall package, which can be placed in the f music roll, or tliev'lilie, so as to be vcarried Y without `inconvenience to the musician.

In setting up ythe stand, the sleeve 26 is moved in a downward direction upon the tubular member or sleeve 2, and over the prov gecting ends of the pin 6, said ends of the pin being passed through the slots or grooves 27, unt-il it rests `upon the upper end of the spring 5', in which position the said sleeve 4 26 is held by giving it a slight turn upon the member or extension 2. A furtherniovement l of the sleeve 26 in a downward direction upon vthe Ymember or extension 2, suitably com` presses the coils of the spring 5 in a manner shown in Figure 9 of the drawings, thereby allowing the pivoted supports or legs 3() to l be spread outwardly, with their sharp or anguiar ends 32 resting against the outer surface-portions of the said -memberor exten- 5 5 n moved in a downward direction upon said sion 2. The locking sleeve is now also member or extension 2, and over the projecting ends of the pin 6, said'ends of the Lpin being passed through the slots oi grooves 35, so that the receiving or socket-portion 3a i e [of the sleeve 33'will rest upon and over the sharp or angular ends 32-of the outwardly r'spread supports or legs 30. Vhen in this position, the seeve 33 is slightly turned, whereby the compresed spring 5 and the projecting endsfof the pin 6,.'will` maintain a rigid supporting relationof these elements, as will be clearly understood from an inspection of said Figure 9 of the drawings. The telescopically arranged members or extensions, as 2 and 3, are now broughtinto their extended relation, show-nin Figure 1 of the drawings, the members or extensions being rigidly locked or maintained in such extended relation, by the act-ion of the bowed portions 11 of the spring-members 9 with slotted portions of the said extensions, as indicated in Figure 6 of the drawings, or by the action of any other suitable locking or retaining means adapted tobe employed in lieu of the said spring-members 9. Next, the pivotally con yiiected members of the music-holder or rack 13`are brought into their opened-out relation shown in said Flgurel, and then connected with the standard of the music-stand by insertion of the angularly bent and fiat end of the uppermost member or extension, as 3, in the receiving space formed between the back of the plate or bar 14 and the strap 15. All of the various elements having thus beeen brought into an assembled relation, a coniplete music-stand ready for use by the musician is thus produced, as will be olearlyevident. To foldl the device, ywhen not wanted for further use, the music-holder or rack is f slipped off from its connected relation with said end-nieinber 12, and closed up, the parts thereof assuming` the positions indicated in Figure 3 of the drawings, and then by a proper manipulation of the spring-members 9, and" of thesleeves 33 anti 26, the various elements of the standard canvbe brought into their closed or collapsed relation, so that the collapsed members of thestandard and the closed members of the music-holder or rack 'can be placed side by side, in the form of a very small package, which can be placed in the music-roll or Satchel of the musician. or it may be placed in the instrument case, or otherwise carried about without inconvenience to the musician. y

Referring now yto Figures 13 and 14 ofthe drawings, inlieu of the locking sleeve 33 heroin-above described, I may use a sleeve 36 which is secured in a fixed position upon the 'ide tubular member or extension 2 by means of a pin 37, or other suitable fastening means, thesaid sleeve 36 being also formed with a cone-shaped receiving portion,as 33, with which the vangular end-portions 32 of the iai. pivoted legs 30 are adapted to be brought iiitoseparable retaining engagement, as will be clearly understood from an inspection of said Figures 13 andk 14.

Iny Figure 15, l have shown still another ik form of locking sleeve 39, also provided with a cone-shaped 'receiving portionllO, for the reception of the angular `end-portions 32 of the pivoted legs 32, said sleeve 39 being provided with a suitable set-screw, as 41, for i securing said sleeve in the desired position upon the tubular extension 2, substantially as shown. Y

Of course I am fully aware, that various changes may be made in the general arrangef ments and combinations of the several de-y vices and parts, as well as in the details of the construction of the said parts, without departing from the scope of the present invention as set forth in the foregoing specification, and as defined in the clauses of the claims which are appended thereto. Hence, I do not limit my present inventio-n to the exact arrangements and combinations of the several devices and parts, as described in the said specification, nor do I confine myself to the exactdetails of the construction of the said parts, as illustrated in the accompanying drawings. v Y

I claim V- l. In a collapsible device of the character described,V the combination of a standard provided with a bead at its lower end, a sleeve mounted Afor sliding and rotary motion on said standard, a coil spring encircling the standard between said bead and sleeve, so as to exert upward moving pressure upon themlatter, a plurality of legs pivoted to said sleeve, so as to fold into positions parallel to the standard lwhile being capable of swinging outward into an'gularly extended relation to said standard, ther upper endsrofsaid legs extending beyond their pivotal points, being Vsecured insaidV standard. andv extending transversely thereof, the ends of said pin pro,-l

jectingbeyond the periphery Oflsaid stand-1 ard and disposed in position yto hold saidk Y' second sleeve in legengaging position Yand Of simultaneously compress said spring between Y the bead and leg-carrying sleeve, each of said sleeves being provided'with a 'pair of diametrically opposite grooves whereby upon rotation of the sleeves their grooves will be, brought into register with` the projectingA ends of said pin and permit the sleeves to be slid into inoperative position on the stand- ,Y
